I used to be stationed in Andersen AFB, Guam. I was working at a warehouse on grave shift (2200-0700). One night I was working the shift alone and I saw a pilot who was completely drenched. Even though there is usually no one around at that time of night, I didn't think much of it because he didn't really look like the traditional "Hollywood version" of a ghost. Also, he seemed a little more happy than I would think a ghost to be. I went up to him and asked if I could help him. He told me that he was looking for the rest of his crew and wanted to know if I would help him. I asked for some information (Mission number, aircraft tail number, etc.) so that I could look it up in our system. I wrote down what he told me and looked it up. Of course I found nothing so I went back to the man to apologize. He wasn't there, again I just thought it was kind of strange. Much to my liking, the rest of the shift went by quickly. When I got home, I emptied out my pants and found the paper where I had written the pilot's information, I decided to look it up on the internet. I believe it to be the mission talked about on this page:
It talks about a plane that crashed off the coast of Guam... In 1952.
